Description: A type of magnetic tape and drive system used for data storage and archiving. A special compression algorithm, known as Digital Lempel Ziv 1 (DLZ1), facilitates storage and retrieval of data at high speeds and in large quantities. The DLT drive writes data to the tape in dozens of linear tracks, usually 128 or 208. DLT increases the data-transfer rates and storage capacities of computer tape drives.
